FIELD OF THE DISCLOSURE

The subject disclosure relates to an apparatus and method for managing events in a computer supported collaborative work environment.

BACKGROUND

Multimedia communication services for more than one user, such as between groups of individuals working together, are known. These services allow multiple persons to work distributed from each other in various locations, and as they collaborate, they work in a virtual environment hosted by technologies that enable the users to create and share data. A baton passing protocol is sometimes employed where whichever participant is “holding the baton” (i.e., they have presenter rights) can perform various actions with respect to the data (e.g., documents) in the virtual environment. However, the baton passing protocol can be inefficient since passing of the baton each time to a new user can be time consuming.

DETAILED DESCRIPTION

The subject disclosure describes, among other things, illustrative embodiments for establishing a Computer Supported Collaborative Work (CSCW) environment that enables multiple users to generate or otherwise cause events to occur in the CSCW environment. The events can be any type of event that changes the CSCW environment such as editing content, adding content, deleting content, changing views, and so forth. A conflict between events generated by different communication devices can be detected and a conflict resolution technique can be applied to determine which, if any, of the events (in whole or in part) is to be implemented in the CSCW environment. The CSCW environment can operate under a non-baton passing protocol. Other embodiments are described in the subject disclosure.

One or more aspects of the subject disclosure include determining a conflict between two or more events and applying conflict resolution, such as a priority determination, control layering, and/or other techniques, so that the conflict can be resolved and the event can be presented at the other communication devices participating in the CSCW environment. The priority determination can be based on different devices having different priorities and/or different events having different priorities. The control layering can be based on different devices being authorized to perform different control commands

One embodiment of the subject disclosure is a communication device including a user interface, a processor coupled with the user interface, and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations. The communication device can perform operations including participating in a communication session over a network with a second communication device that is remote from the communication device, where the communication session comprising a computer supported collaborative work environment utilizing a non-baton passing protocol. The communication device can present content at a display device, where the content is presented by the second communication device at a second display device. The communication device can receive first user input at the user interface, where second user input is received by the second communication device, where the content is adjusted according to the first and second user input to generate adjusted content, where the first user input is associated with a first group of control commands, where the second user input is associated with a second group of control commands, where the processor is prohibited from performing the second group of control commands, and where the second communication device is prohibited from performing the first group of control commands The communication device can present the adjusted content at the display device.

One embodiment of the subject disclosure is a machine-readable storage device, comprising executable instructions that, when executed by a processor of a communication device, facilitate performance of operations. The processor can participate in a communication session over a network with a second communication device that is remote from the communication device, where the communication session comprises a computer supported collaborative work environment utilizing a non-baton passing protocol. The processor can present content at a display device, where the content is presented by the second communication device at a second display device. The processor can present a first graphical pointer at the display device and can receive first user input. The processor can adjust the first graphical pointer according to the first user input to generate a first adjustment to the first graphical pointer and can presenting, at the display device, the first adjustment to the first graphical pointer while presenting the content. The processor can present, at the display device, a second graphical pointer at the display device while presenting the first adjustment to the first graphical pointer and while presenting the content, where the second communication device receives second user input, and where the second communication device adjusts the second graphical pointer according to the second user input to generate a second adjustment to the second graphical pointer. The processor can present, at the display device, the second adjustment to the second graphical pointer while presenting the first adjustment to the first graphical pointer and while presenting the content, where the first and second graphical pointers are visually distinguishable, and where the second graphical pointer includes identification information associated with the second communication device.

One embodiment of the subject disclosure is a method including facilitating establishing, by a system including a processor, a communication session over a network between a group of communication devices including first and second communication devices, where the communication session comprises a computer supported collaborative work environment utilizing a non-baton passing protocol, where content is presented via the communication session by the group of communication devices at a group of display devices. The method can include receiving, by the system from the first communication device, first adjustment data generated by the first communication device according to first user input at the first communication device, where the first adjustment data is representative of a first adjustment made by the first communication device to the content according to the first user input to generate first adjusted content. The method can include receiving, by the system from the second communication device, second adjustment data generated by the second communication device according to second user input at the second communication device, where the second adjustment data is representative of a second adjustment made by the second communication device to the content according to the second user input to generate second adjusted content. The method can include determining, by the system, a conflict between the first and second adjustments. The method can include selecting, by the system, the first adjustment data according to a priority determination indicating that the first adjustment has priority over the second adjustment. The method can include providing, by the system to the second communication device, the first adjustment data to enable the second communication device to generate and present the first adjusted content at a second display device of the group of display devices.

One or more aspects of the subject disclosure include monitoring feedback from a recipient device where the feedback indicates whether a content change generated by a source device has been presented at the recipient device. According to the feedback information, the source device can present an indicator representing the presentation of the content change at the recipient device. In this example, the user of the source device where the content change was generated will then know when the other user of the recipient device is viewing the content change. The indicator can be provided utilizing various techniques and in various forms. For instance, a format of the content change can be adjusted to represent when the recipient device has presented the content change. In other embodiments, the indicator can be a separate icon or other indicia that indicates when the content change has been presented by the recipient device. In one embodiment, the icon or indicia can identify the recipient device and can change according to whether or not the content change has been presented at the recipient device. For instance, an icon identifying the recipient device can have a line through it, can be transparent, and/or can be the color red prior to the presentation of the content change at the recipient device. Responsive to the recipient device presenting the content change (and based on feedback information being provided by the recipient device), the icon can have the line removed, can become non-transparent, and/or can be the color green. This process can be repeated each time there is a content change by the source device or by another device that is participating in the communication session.

The CSCW environment enables individuals to work, design, create artifacts, share applications, and/or gaming (as well as any other collaborative interaction) via various multimedia mediums and multimodal input devices. Their collaborations in a virtual working environment can include: working with multimedia documents (e.g., text, image, video, audio files, and so forth), working on digital whiteboards, interacting via voice and video communications, and so forth.

One embodiment of the subject disclosure is a communication device including a user interface, a processor coupled with the user interface, and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations. The processor can participate in a communication session over a network with a second communication device that is remote from the communication device and can present content at a display device. The processor can receive user input at the user interface and can adjust the content according to the user input to generate adjusted content. The processor can present the adjusted content at the display device in real time responsive to the receiving of the user input and can provide adjustment data over the network, where the adjustment data is representative of the adjusting of the content according to the user input, and where the adjustment data enables the second communication device to generate and present the adjusted content at a second display device connected with the second communication device. The processor can receive a feedback signal indicating that the second communication device has presented the adjusted content at the second display device. The processor can present a feedback indicia at the display device responsive to the receiving of the feedback signal, wherein the feedback indicia indicates that the second communication device has presented the adjusted content at the second display device.

One embodiment of the subject disclosure includes a machine-readable storage medium, comprising executable instructions that, when executed by a processor of a communication device, facilitate performance of operations. The processor can participate in a communication session over a network with a group of other communication devices and can present content at a display device, where the content is presented by the group of other communication devices at a group of other display devices. The processor can receive adjustment data over the network from a second communication device of the group of other communication devices, where the adjustment data is representative of an adjustment of the content according to user input received at the second communication device, and can adjust the content according to the adjustment data to generate adjusted content. The processor can present the adjusted content at the display device and can provide feedback information over the network indicating that the adjusted content has been presented by the communication device at the display device, where the providing of the feedback information enables the second communication device to present a feedback indicia at a second display device of the group of other display devices, and where the feedback indicia indicates that the communication device has presented the adjusted content at the display device.

One embodiment of the subject disclosure includes facilitating establishing, by a system including a processor, a communication session over a network between a group of communication devices including first and second communication device. The system can receive, from the first communication device, adjustment data generated by the first communication device according to user input at the first communication device, where the adjustment data is representative of an adjustment made by the first communication device to content according to the user input to generate adjusted content, where the content is presented by the group of communication devices at a group of display devices. The system can provide, to the second communication device, the adjustment data to enable the second communication device to generate and present the adjusted content at a second display device of the group of display devices. The system can receive, from the second communication device, feedback information indicating that the second communication device has presented the adjusted content at the second display device. The system can provide, to the first communication device, a feedback signal that enables the first communication device to present a feedback indicia at a first display device of the group of display devices, where the feedback indicia indicates that the second communication device has presented the adjusted content at the second display device.

The exemplary embodiments can also include one or more features described in U.S. patent application Ser. No. 14/700,729, filed Apr. 30, 2015, by Riecken et al. entitled “Apparatus and Method for Providing a Computer Supported Collaborative Work Environment.” All sections of the aforementioned application(s) are incorporated herein by reference in its entirety.

FIG. 1 depicts an illustrative embodiment of a system 100 that provides for content collaboration, such as via a CSCW environment that enables a user to know when local changes made at the user's device are presented at other devices. System 100 can include a group of communication devices 116 that participate in a communication session that establishes the CSCW environment. Any number of communication devices 116 and any type of communication devices can be utilized in system 100, including desktop computers, laptop computers, tablets, mobile phones, set top boxes, televisions and so forth. In one embodiment, a conference server 130 can be utilized to manage all or a portion of the CSCW environment over a network 132. The conference server 130 can be a single computing device, such as a centralized or a dedicated server, or can be a number of devices, such as in a distributed control environment. In one embodiment, the conference server 130 can be a network device. In another embodiment, the conference server can be a user device, such as one of the communication devices 116 that is a participant in the CSCW environment and also manages some of the aspects of the CSCW environment. In one embodiment, the conference server 130 can be in communication with a database 135 which is populated with persistent state information of multimedia actions and events occurring in the CSCW environment.

In one embodiment, the conference server 130 can setup, manage, and/or breakdown multiparty virtual multimedia working rooms/sessions that support input from multiple participants (via devices 116) who generate (simultaneously or separately) input events (e.g., typing, editing, drawing, dragging, and so forth). In one embodiment, the input events can be serialized to create partial orderings of the work activities generated by the participant devices 116. In one embodiment, a First-In-First-Out (FIFO) protocol, such as operated by FIFO server components of the conference server 130, can be employed which serializes a diversity of input events from the participant devices 116. In one embodiment, the events can be a diversity of different multimedia processes to be performed.

The conference server 130 can perform functions 162 (such as via execution of a set of machine-readable instructions) which include managing feedback of some or all actions being performed by some or all participants in the CSCW environment and/or supporting baton passing and/or non-baton passing protocols in the CSCW environment. In one embodiment, all actions performed by any of the participant devices 116 in the CSCW environment (e.g., which adjust the collaborative presentation) can be monitored for presentation at all of the devices and feedback can be provided to one or more the devices 116, such as the source device that generated the particular adjustment to the content.

System 100 can deliver anytime-anywhere multimedia communication services between groups of participants working together. Multiple participants, via devices 116, can work in the same or various locations. As the participants collaborate, they can work in a virtual environment (i.e., the CSCW environment) that enables the participants to create, modify and/or share work artifacts (e.g., documents, designs, execution of software applications, and so forth). In one embodiment, system 100 can employ a baton passing protocol whereby whichever participant is “holding the baton” indicating that they have presenter rights, can perform various actions (e.g., create, edit, save, delete, and so forth) on the documents and applications present in the CSCW environment. In another embodiment, system 100 enables all or some of the participants to perform all or some of the legal actions associated with the CSCW environment without “holding the baton” such that there is no need for a baton granting presenter's rights. Thus participants at their discretion can elect when they wish to work with a baton passing protocol or not. This provides greater flexibility and efficiencies in team interactions; for example, tasks can be parallelized during meetings. It can also be observed that participants would be able to perform and work together in a more natural setting, typical to a real-world situation.

In one embodiment, the conference server 130 can manage feedback delivered to an individual performing an action and/or all or some of the other participants observing the action. The conference server 130 can serialize sets of inputs occurring from the multiple actions being performed (e.g., simultaneously) by participants at the devices 116. The conference server 130 can process the input of multiple actions in a FIFO manner which enables organizing the observed outcome of multiple simultaneous actions in a serialized result observed by all participants.

System 100 can provide feedback for an individual who performs an action (e.g., typing a sentence, drawing a line, presenting a PowerPoint slide, and so forth). In one embodiment, as the individual makes an adjustment to the CSCW environment (e.g., introduces a PowerPoint slide, draws a line on a document currently in the work environment, and so forth), completion of the action requires feedback that the action was performed correctly on the individual's local device and feedback that the result(s) of the action were propagated and presented (or otherwise performed) correctly on all the participants' devices.

In one embodiment, immediate feedback for the user performing the action on their local device can be provided and feedback indicating when the results of the action appear on all the participants' local devices is monitored and then presented at the local device (i.e., the source device that made the change to the CSCW environment). For example, a user can draw a line, type a character, write with digital ink and so forth and the visual result of drawing or typing on the local device of that user is immediate without delay, thus providing a natural environment for the user.

System 100 also accounts for latency introduced in propagating the results of the action to the various remote participant devices. Feedback can be provided as to when the remote participants can view the actions performed. For example, when a participant introduces a new PowerPoint slide to the CSCW environment, this participant can determine when to discuss the slide once the feedback mechanism indicates that the slide has been transmitted and is viewable on the remote devices of the other participants.

Referring additionally to FIG. 2 , communication device 116A is illustrated in which content (an image or a drawing of an automobile) is illustrated. The content can be presented by all of the devices 116, as shown in FIG. 1 . The user of communication device 116A makes an adjustment 216 to the content, which in this case is changing the shape of the back end of the automobile. As adjustment 216 is inputted into communication device 116A (e.g., via a keyboard, mouse, stylus, or any other user input) it is presented immediately or in real time at the display of communication device 116A so that the user can see the changes as they are being made. In one embodiment, the adjustment 216 is initially presented in a first format (e.g., as a dashed line) as a non-presentation indicia 250 to indicate that the adjustment 216 has not yet been presented at one or more other devices (e.g., 116B, 116C, 116D) that are participating in the CSCW environment.

Referring additionally to FIG. 3 , once the adjustment 216 has been presented at the one or more other devices (e.g., 116B, 116C, 116D) that are participating in the CSCW environment then the adjustment 216 can be presented in a second format (e.g., as a solid line) as a presentation indicia 350 to indicate that the adjustment 216 has been presented at the one or more other devices. This example describes the format change as being broken lines to solid lines, but the format changes can be of various types including color changes, font changes, size changes, motion changes (e.g., jittering line to stable line), blinking changes, and so forth. In one embodiment, the presentation of the presentation indicia 350 to indicate that the adjustment 216 has been presented at the one or more other devices can be done only after the feedback from the communication devices 116B-D indicates that the adjustment 216 has been presented at all of the devices 116B-D. In another embodiment, the non-presentation indicia 250 and the presentation indicia 350 can include a range of formats to indicate which of the communication devices 116B-D has been presented the adjustment 216. For example, the initial non-presentation indicia 250 can be multi-colored (e.g., different portions of the adjustment 216 having different colors) with each of the colors representing one of the other devices 116B-D. As the adjustment 216 is presented at each of the other devices 116B-D, the corresponding color for that particular device can be changed to black. Once the adjustment 216 has been presented at all of the communication device 116B-D, the entire adjustment 216 can be black representing that all of the devices have presented the adjustment 216. In one embodiment, a color code can be presented so that the user of communication device 116A knows which devices have or have not presented the adjustment 216. This particular example is described with respect to utilizing multiple colors, but the exemplary embodiments can be utilize other format changes, such as blinking of the light at variable speeds (e.g., faster blinking indicating fewer devices have presented the adjustment 216 and faster blinking indicating more of the devices have presented the adjustment 216. In this example, the speed of the blinking can be indicative of the number of devices 116B-D that have presented the adjustment 216, although the identity of those devices may not be presented to the user of communication device 116A. In other embodiments, the changing of the format (e.g., over a range of formats such as the multi-color example above) can identify which of the communication devices 116B-D have presented the adjustment 216.

Referring to FIG. 4 , communication device 116A is illustrated in which the adjustment 216 to the content is illustrated (e g , immediately when the user of device 116A inputs the adjustment) and a group of feedback icons 450 are presented to indicate whether the adjustment has been presented at the other devices 116B-D. In this embodiment, the feedback indicia is separate feedback icons for each of the other communication devices 116B-D participating in the CSCW environment. The icons 450 can identify the particular users of each of the devices 116B-D and/or can be distinct from each other so as to identify the particular device 116B-D. The icons 450 can change to indicate presentation or a lack of presentation of the adjustment 216, such as having a line through the icon when the adjustment has not yet been presented but removing the line once the presentation has been performed by the particular other device. Other changes in the icon can be used to signify a presentation or a lack of presentation of the adjustment 216, such as changing from red to green colors.

In one embodiment, the icons 450 can also provide other information associated with the particular device 116B-D (e.g., established connection, type of device, bandwidth, and so forth). In another embodiment, the icons 450 can be a selectable link to enable other operations associated with the CSCW environment, such as selecting an icon of a device that is having difficulty receiving and presenting adjustment 216 so that the server 130 can determine if another connection is available for that particular device.

In one or more embodiments, system 100 can employ multimedia application device drivers to perform various operations including: performing multimedia actions (e.g., drawing) on the local client device of the originating participant performing the multimedia action; performing a feedback-multimedia-action on the local client device of the originating participant who performed the initial multimedia action where the feedback communicates to the originating participant that the initial action has been transmitted and presented to the remote participants on their remote client devices; performing the necessary functions to transmit and present to all remote participants in a CSCW working session a multimedia action performed by a participant; and/or performing history functions by maintaining persistent state information of the sequence of all events/actions occurring during a CSCW working session.

Referring to FIG. 5 , system 500 is illustrated in which communication devices 116A-D participate in a CSCW environment that is being managed in whole or in part by conference server 130. Upon determination of a failure to present the adjustment 216 at device 116D, the conference server 130 can attempt to adjust the connection 519 that the device is utilizing for the CSCW environment. The adjustment of the connection can include adjusting parameters of the connection (e.g., bandwidth, network resources, and so forth) and/or can include establishing another connection 520 for the communication device 116D.

FIG. 6 depicts an illustrative embodiment of a method 600 used to establish and/or facilitate providing a shared environment (e.g., a CSCW environment) for multiple communication devices, such as devices 116A-D. Method 600 can provide feedback of all actions being performed by all participants in a CSCW environment, and can support baton passing and/or non-baton passing protocols in the CSCW environment.

Method 600 can allow all participants to freely perform all legal actions without “holding the baton” so that there is no need for a baton granting presenter's rights. Thus participants at their discretion can elect when they wish to work with a baton passing protocol or not. This provides greater flexibility and efficiencies in team interactions; for example, tasks can be parallelized during meetings. It can also be observed that participants would be able to perform and work together in a more natural setting, typical to a real-world situation. Method 600 can also provide feedback to: (1) an individual performing an action and/or (2) all the other participants observing the action.

Method 600 can begin at 602 where a communication session is established over a network between a group of communication devices, such as devices 116A-D. At 604, local adjustments can be monitored, such as by the conference server 130. For example, adjustment data can be received by the conference server 130 which was generated by a first communication device (e.g., device 116A) according to user input at the first communication device. The adjustment data can be representative of an adjustment made by the first communication device to content (e.g., drawing a line in a diagram, adding a slide, recording audio, and so forth) according to the user input to generate adjusted content. The content can be presented by the group of communication devices at display devices as part of the CSCW environment.

At 606, feedback can be obtained indicating which of the other devices have presented the adjustment to the content. For example, the conference server can be in communication with the other devices and can receive feedback (e.g., from the other devices once the adjustment has been presented by the other devices (e.g., individually from each of the other devices). At 608, feedback signal(s) can be provided to the device that generated the content adjustment (e.g., conference server 130 transmitting a feedback signal to the communication device 116A). The feedback signal can be indicative of completion of the presentation of the content adjustment at the other devices.

At 610, a determination can be made as to whether the content adjustment has been presented at all of the other communication devices. If so, method 600 can return to 604 to continue monitoring for content adjustments. If one or more of the other communication devices has not presented the content adjustment, then at 612 the conference server can attempt to make connection adjustments for those particular communication devices, such as establishing other connections.

In one embodiment, a determination that feedback information has not been received from a particular communication device can be according to expiration of a time period. In another embodiment, the CSCW environment can be managed according to a first-in-first-out protocol. In one embodiment, the providing of the feedback signal(s) enables the device which is the source of the content adjustment to present a feedback indicia that includes changing a presentation format of the adjusted content, where the presentation format comprises a color, a font, a size, a motion, a blinking, or any combination thereof.

FIG. 7 depicts an illustrative embodiment of a method 700 used to establish and/or facilitate providing a shared environment (e.g., a CSCW environment) for multiple communication devices, such as devices 116A-D. Method 700 can provide an efficient technique for managing events in a non-baton passing protocol in the CSCW environment. Method 700 can allow all or some of the participants to freely perform all or some of the legal actions without “holding the baton” so that there is no need for a baton granting presenter's rights. Method 700 can be combined in whole or in part with all or portions of method 600, such as to provide feedback to: (1) an individual performing an action and/or (2) all the other participants observing the action.

Method 700 can begin at 702 where a communication session is established over a network between a group of communication devices, such as devices 116A-D. The communication session can be a CSCW environment employing a non-baton passing protocol. At 704, local events can be monitored, such as by the conference server 130. The local events can be any type of an event that alters or adjusts the CSCW environment including adjustments to the content, adding new content, moving a pointer, navigation changes (e.g., rotation of the view), and other CSCW environment changes. For example, communication device 116A may begin to draw (a first event) resulting in content adjustment 216 being presented at the display device of communication device 116A. Communication device 116B can be initiating a second event, such as changing a slide that is being shown in the CSCW environment. At 706, a determination can be made as to whether the first and second events are in conflict. If there is no conflict then the first and second events can be provided to the other communication devices for presentation. However, in this example, since communication device 116A is trying to draw on the content of the presented slide while communication device 116B is trying to replace that particular slide with another slide, a conflict does exist.

At 708, conflict resolution can be implemented, such as by conference server 130, to resolve the conflict between the first and second events (or any number of events) and at 710 adjustment data representing the event (which may be resolved via the conflict resolution) can be provided to the other devices of the CSCW environment. In one embodiment, the conflicting events can be events that overlap in time.

In one embodiment, the conflict resolution can be based on a priority determination. For example, the priority determination can be based on types of events, such as editing content taking priority over replacing the entire content with another slide with other content. A priority list can be generated (with or without user input) to assist in managing the conflict resolution, such as creating a prioritizing order for various events including content edits, content view changes, navigation in the window presenting the content, adding new content, changing a slide to show new content, adding audio, changing audio, and so forth. In another example, the priority determination can be based on the particular device causing the event, such as providing communication device 116A with priority over communication device 116B for all events or for designated events.

In one embodiment, the conflict resolution can be based on designating layers of control over the CSCW environment to the communication devices 116A-D. For instance, communication device 116A can be authorized to utilize a first group of control commands (e.g., content editing, adding content, and replacing a slide to provide new content) while communication device 116B can be authorized to utilize a second group of control commands (e.g., navigating a pointer, panning, rotating and/or zooming the view of the content). In this example, the authorized control commands can be performed by one of the devices without preventing performance of the authorized control commands of the other of the devices. In one embodiment, unauthorized events (i.e., the communication device is not designated to perform the particular control command) can be prohibited at the unauthorized communication device or can be performed (in whole or in part) but not provided to the other devices, such as presenting an authorized edit of the content at the device making the unauthorized edit but not providing the unauthorized edit to any of the other devices. In another embodiment, a message or other prohibition indicia can be presented at the communication device that is attempting to make the unauthorized edit. These examples describe unauthorized edits, but the exemplary embodiments are applicable to any type of unauthorized event caused by a communication device (e.g., in response to user input) that does not have authorization to utilize the particular control command

In one embodiment, conflict resolution can be according to other techniques, such as which device initiated the event first. In another embodiment, the conflict resolution can be independent of the timing of the initiation of the events. In one embodiment, the conflict resolution can be according to a combination of techniques, such as providing different devices with authorization to perform different groups of control commands and resolving any conflicts that occur between control commands of the different groups based on a priority determination, such as editing content from a first group of control commands taking priority over rotating the view of the content from a second group of control commands

In another embodiment, conflicted events can be cancelled or delayed. For example, a first event editing the content in one particular way may take priority over a second event editing the content in another particular way, where the first event is provided to the other communication devices for presentation and the second event is cancelled or otherwise not distributed to the other devices. In another embodiment, a first event caused by a first communication device editing the content may take priority over a second event caused by a second communication device rotating the view of the content, where the first event is provided to the other communication devices for presentation and the second event is delayed and then provided to the other devices. In this example, a third communication device may receive and present the edited content (based on the first event) and then after a particular time period the third communication device may receive and present the rotated view of the edited content.

Referring to FIG. 8 , communication device 116A is illustrated in which the adjustment 216 to the content is illustrated (e.g., immediately at the local device when the user of device 116A inputs the adjustment). A first graphical pointer 816A (e.g., any visual symbol that is manipulated via user input such as an arrow, a cross, and so forth) is presented which is controllable via user input at the communication device 116A. In this example, the pointer 816A has been used to generate the content adjustment 216 (i.e., the line drawing). A second graphical pointer 816B is presented (by the communication device 116A) which is controllable via user input at the communication device 116B. The pointers 816A and 816B can be visually distinct. In one embodiment, the pointers 816A and 816B can include identification information 850A, 850B, respectively. In one embodiment, the identification information can identify the particular communication device controlling the pointer, the user of the particular communication device controlling the pointer, and/or a username supplied via the particular communication device controlling the pointer. In another embodiment, the identification information can identify the authorized controls associated with the particular communication device such as communication device 116A being authorized to edit the content and communication device 116B being authorized to navigate.

By way of these interfaces, unicast communications can also be invoked between the media processors 906 and subsystems of the IPTV media system for services such as video-on-demand (VoD), browsing an electronic programming guide (EPG), or other infrastructure services.

A satellite broadcast television system 929 can be used in the media system of FIG. 9 . The satellite broadcast television system can be overlaid, operably coupled with, or replace the IPTV system as another representative embodiment of communication system 900. In this embodiment, signals transmitted by a satellite 915 that include media content can be received by a satellite dish receiver 931 coupled to the building 902. Modulated signals received by the satellite dish receiver 931 can be transferred to the media processors 906 for demodulating, decoding, encoding, and/or distributing broadcast channels to the media devices 908. The media processors 906 can be equipped with a broadband port to an Internet Service Provider (ISP) network 932 to enable interactive services such as VoD and EPG as described above.

In yet another embodiment, an analog or digital cable broadcast distribution system such as cable TV system 933 can be overlaid, operably coupled with, or replace the IPTV system and/or the satellite TV system as another representative embodiment of communication system 900. In this embodiment, the cable TV system 933 can also provide Internet, telephony, and interactive media services. System 900 enables various types of interactive television and/or services including IPTV, cable and/or satellite. The subject disclosure can apply to other present or next generation over-the-air and/or landline media content services system.

Some of the network elements of the IPTV media system can be coupled to one or more computing devices 930, a portion of which can operate as a web server for providing web portal services over the ISP network 932 to wireline media devices 908 or wireless communication devices 916.

Communication system 900 can also provide for all or a portion of the computing devices 930 to function as a conference server 930, similar to conference server 130 of FIG. 1 (herein referred to as server 930). The server 930 can use computing and communication technology to perform function 962, which can include among other things, management of different events caused by different devices in a non-baton passing protocol, management of feedback to a source device to indicate when content adjustments have been shown at recipient devices, and/or adjustments to connections for recipient devices that have failed to or are having difficulty presenting content adjustments. For instance, function 962 of server 930 can be similar to the functions described for server 130 of FIG. 1 in accordance with methods 600 and 700. The media processors 906 and wireless communication devices 916 can be provisioned with software functions 964 to utilize the services of server 930. For instance, functions 964 of media processors 906 and wireless communication devices 916 can be similar to the functions described for the communication devices 116A-D of FIG. 1 in accordance with methods 600 and 700, and can include participating in a CSCW environment with non-baton passing protocol, limiting actions to authorized control commands designated to the particular device, providing feedback data to the conference server 930 and/or presenting feedback indicia indicating which recipient devices have shown the content adjustments.
